Features

For over 50 years, Mitsubishi has remained at the forefront of the mini split industry thanks to their dedication to providing efficient, user-friendly comfort solutions. Part of Mitsubishi's hyper-heating product line, the MZ-FH15NA is a packaged single zone heat pump mini split system designed to bring high-efficiency zoned comfort to homes in frigid climates. The wall mounted indoor unit, MSZ-FH15NA, boasts a functional design, and operates at volumes as low as 25 dB. Thanks to the included mounting plate, it is easy to install on nearly any wall. The outdoor condenser uses some of the most advanced technology available to modulate temperature without the energy-wasting overshoots and short-cycling associated with simpler systems. With an included wireless remote controller, this system is the perfect combination of convenience and comfort for any application in a sub-freezing environment.

Precision Temperature Control Technology

The MUZ-FH15NA outdoor condenser includes inverter technology and an electronic linear expansion valve. By adjusting compressor speed and refrigerant flow, output can be matched to the zone for precise temperature control and improved efficiency.

i-see Sensor 3D

The MSZ-FH15NA's i-see Sensor 3D monitors its zone for fluctuations in temperature. If it detects an underserved area, the MSZ-FH15NA will temporarily direct airflow to that zone. It also enters energy saving mode if no human heat signatures are detected.

H2i Technology

Low or negative ambient temperatures don't bother the MUZ-FH15NA. It is rated for 100% heating capacity at 5 degrees F and continues to provide heating in outdoor conditions as low as -13 degrees F.

Advanced Filtration System

With three unique filters inside the MSZ-FH15NA, the air in your zone is not only being conditioned, but it is also actively being cleaned. These filters remove odors, nanoparticles, and bacteria from re-entering your home.

Mitsubishi's Smart Set function allows you to save a cooling and heating profile, each consisting of temperature, fan speed, and airflow direction. These are easily activated with the Smart Set button on the remote controller.

Powerful Mode

The powerful setting on the MSZ-FH15NA makes it easy to get your zone to the perfect temperature quickly. When activated, the unit temporarily increases refrigerant flow and fan speed to provide quick comfort through rapid heating or cooling.

Econo Cool Mode

By slowly adjusting the cooling set point and swinging the horizontal vanes, the MSZ-FH15NA can improve the efficiency of cooling operations without compromising the comfort provided.

Dehumidification

When the indoor unit runs in dry mode, the coil's temperature stays just below the dew point of the return air, removing unwanted moisture. This improves comfort and reduces the chance of mold growth and other property damage in the conditioned space.

Vane Control

Optimal air flow can be achieved with the MSZ-FH15NA with independent vane control and two vane control options, standard and wide. Auto mode selects the best vane position based on operating mode while swing mode cycles through each vane position.

Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.

Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris.

Adding these accessories to your order will provide a complete, ready-to-install mini split system. All Mini Split Systems require one Primary Mini Split Installation Kit. You may also require one or more Secondary Installation Kits if you have a Multi-Zone system. You will need a Secondary Installation Kit for each additional indoor unit.

Are the filters washable?

Douglas H

from Alabama

July 10, 2017

Answer

The Mitsubishi MZ-FH09NA system has 3 different filters each with slightly different maintenance requirements. The primary air filter should be either vacuumed or rinsed with water every other week, the anti-allergen filter should be vacuumed or rinsed with warm water every 3 months, and the deodorizing filter should also be vacuumed or rinsed with warm water every 3 months. The latter two filters will also need to be replaced periodically. Complete details about filter maintenance and replacement can be found in the operation manual on page En-11.

+−

What is recommended square footage for this FH06 model?

Anton

from Virginia

October 07, 2016

Answer

Sizing depends on a number of factors besides the size of the room being heated or cooled. These include the quality of insulation, the number and size of the exterior walls, the size and quality of the windows, and the climate among other factors. To provide the best estimate possible we recommend using our Mini Split Sizing Wizard.

+−

What size breaker does this 15,000 BTU unit require?

Peter

from Massachusetts

September 30, 2016

Answer

Mitsubishi recommends using a 20A breaker for the MZ-FH15NA. Make sure you verify the breaker sizing with your installer and also with any applicable building codes and regulations. These may sometimes supersede the manufacturer's recommendation.

+−

What wall mounted programmable control options are there for the MZ-FH systems?

Adam

from Massachusetts

August 11, 2016

Answer

You can use three different adapters / controls to program the wall mounted unit:

The first option has the thermostat included. The second option will require your own thermostat. The third option will require a smartphone or tablet.

+−

Does the unit automatically shut off once the set temperature is reached, or does it just run constantly?

Lindsay

from Texas

July 30, 2016

Answer

This system is designed to run constantly to maintain the set temperature. Once it reaches the set-point, both the outdoor unit's compressor and the indoor unit's fan slow to a reduced speed. The ability to slow down the compressor is one of the major benefits of inverter technology. It helps efficiency because compressor startup uses disproportionately more energy than operation.

+−

In which temperatures can it do the cooling and heating?

Nihan

from Hawaii

July 22, 2016

Answer

In the cooling mode, the system can operate in outdoor temperatures between 14° F and 115° F.

In the heating mode, the system can operate in outdoor temperatures between -13° F and 75° F. It can deliver up to 100% of the rated heating capacity at 5° F.

+−

Can this unit be used for a business?

Joe

from New York

December 30, 2015

Answer

Yes, there is no reason the Mitsubishi M-series units can't be used in an office or store front. However if you are using the unit to cool equipment, such as a server, that requires cooling 24 hours a day 365, I would suggest using a Mitsubishi P-Series unit. These are more robust and will perform better under these conditions than the M-Series units.

+−

Is this unit both a heat source and AC?

Russ

from Washington

November 16, 2015

Answer

Yes, the Mitsubishi MZ-series heat pump system will provide both cooling and heating for your space. In fact, the FH is the Hyper-Heating product that will be able to provide heat while outdoor temperatures reach down to -14F.

+−

Do these come with FREON / Refrigerant straight from the factory?

Michael

from Colorado

November 16, 2015

Answer

Yes, Mitsubishi single zone heat pumps will come pre-charged with enough R-410a refrigerant for up to 25' of lineset. The system will need to be purged and vacuumed prior to releasing the refrigerant. If the pipe length exceeds 25', your installer will need to add additional refrigerant.

+−

I have 11' walls. How high should I mount the indoor unit?

Bill

from Washington

November 16, 2015

Answer

You can install Mitsubishi Wall Mounted indoor units anywhere between 63" from the floor to 3" from the ceiling. Generally, you'll want to install the indoor unit high on the wall where air can distribute over the entire room.

+−

How many hours should it take to install this unit in a sunroom that is under construction?

Jim

from North Carolina

September 10, 2015

Answer

A basic installation without any obstructions or complications can take as little as 4 hours to complete. Keep in mind that I've never seen your sunroom, so you should definitely have this conversation with your contractor!
